Abstract
A remote program monitor method and system using a system-under-test microcontroller for self-debug comprises a system-under-test (SUT) that includes a read-only memory (ROM) and a microcontroller for executing a program under test. The microcontroller has an interrupt input, wherein one or more enable debugger signals received at the interrupt input causes the microcontroller to execute a debugger program contained in the ROM. The SUT is connected with a host computer over a standard serial connection. When the SUT receives one or more debugger signals as an interrupt input, the signal causes the microcontroller to execute a debugger program contained in the ROM.
